Analysis of heat and power systems with the use of heat pumps with ground-based heat exchangers integrated into the foundation

Abstract

Ukraine, as part of Europe, is undergoing energy crisis due to the significant increase in the cost of energy resources, which leads to a reduction in production, deterioration of the microclimatic conditions in the premises, an increase in the cost of finished products and large losses, both in agriculture and in industry. One of the methods to solve this problem is to increase energy preservation and energy efficiency, as well as comfort of buildings and structures with alternative energy sources, heat and power systems using heat pumps, ground heat exchangers integrated into the foundation, energy piles.
This paper represents the analysis and classification of existing heat-energy systems with the use of heat pumps. It was found that one of the perspective directions of the research is the heat-energy systems with ground heat exchangers integrated into the foundation, energy piles. These energy systems can be classified according to technological and structural parameters. The negative characteristics of these systems identified may include: depth dependence of soil freezing, the complexity of the installation process, low corrosion resistance of metal frames and heat exchangers. The advantages of these systems include: the use of a renewable energy source, ground energy, groundwater, heat loss through the foundation and the basement of the building, energy communications, the possibility of use both for cooling and heating of premises, integration in the heat exchanger pile, with other power systems and hot water supply. The use of these systems in dairy cattle farms is a promising area of research.
